As per one of the KZK creative's caption on one of their recent posts, 'Having a soft heart in a cruel world is courage,not weakness'.
And now SP has come up with this latest post

Isn't it now clear that neither the CVs nor the channel is planning to change Prerna's characterisation. Which means, Prerna Sharma will continue to be the selfless girl with a soft heart.
Whenever she is asked if she likes to change anything in her costars, Eri use to answer that, if you want a change in a person then that person will never be the same person anymore; so she prefers to accept a person as he/she is. Same is the case here.
